Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication technologies face limitations in communication range due to factors like transmission power, antenna design, and environmental interference, which can lead to energy inefficiency and thermal issues when trying to enhance range.
Innovation Solution
The method involves scanning within predefined ranges by two wireless devices to determine lists of connectable router devices, comparing these lists to select a target router with strong signal strength, and establishing communication through this relay device, even if one device moves out of the initial communication range.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If transmission power is increased to enhance communication range, then communication range is improved, but energy consumption increases and excessive heat is generated
Solution Approach 1:
The patent introduces a relay device (router) as an intermediary to extend communication range. Instead of increasing transmission power directly, the system uses the relay device to forward messages between devices that are out of direct communication range, thereby achieving range extension without additional energy consumption from the original devices.
Solution Approach 2:
The communication path is segmented into multiple hops through the relay device. Rather than requiring a single direct connection with high transmission power, the communication is divided into separate segments (device-to-relay, relay-to-device), each operating at lower power levels.
2Length of stationary object
If transmission power is increased to enhance communication range, then communication range is improved, but excessive heat is generated
Solution Approach 1:
The relay device acts as an intermediary that handles the burden of extended range communication. By offloading the relaying function to a dedicated device, the original devices can maintain lower transmission power and thus generate less heat, while still achieving extended communication range through the relay.
3Length of stationary object
If devices scan for connectable devices to establish relay communication, then communication range is extended, but communication overhead and time increase
Solution Approach 1:
Devices perform scan operations in advance to build lists of connectable relay devices before actual communication is needed. This preliminary action allows the system to quickly select and establish relay connections when range extension is required, reducing the time penalty during actual communication events.

AI summary
The present disclosure addresses a system and a method for enhancing a communication range between a first device and a second device communicatively coupled to the first device. The method includes scanning within a first range of the first device to determine a first list of connectable devices; instructing, by the first device, the second device to scan within a second range of the second device to determine a second list of connectable devices; receiving, by the first device, the second list of connectable devices from the second device; determining, by the first device, a target device based on the first list of connectable devices and the second list of connectable devices; and establishing, by the first device, a communication with the second device via the target device.
